概要

Timing belts differ both from their tooth profiles (trapezoidal, curved, etc.. ) but also from their shapes along width (spur, spur stepwise, helical, etc.. ). In addition, meshing of timing belts differ as some of timing belts are pressed on tips of pulley teeth while others are pressed in tooth roots of pulley. Therefore, constant optimization requirements ask for careful comparisons of performances of such timing belts. In this paper, one trapezoidal tooth profile will be considered with an initial pitch of 10 millimeters and different shapes along width such as spur, spur stepwise, circular will be tested. A test procedure was also defined with dynamic transmission error and noise measurements, dynamic torques and efficiency as well as temperature measurements. Tests were performed on an original test rig, sensor devices and data acquisitions will be also described. Further, results will be synthesized for all the timing belts in order to make comparisons. Finally, a discussion will allow us to make relations between design parameter influences and physical phenomena.
